Source-Noise in Radio Synthesis Images of Polarised Sources

  • Conference paper
Very High Angular Resolution Imaging

Part of the book series: International Astronomical Union / Union Astronomique Internationale ((IAUS,volume 158))

Abstract

We discuss the distribution of Source-and receiver-noise in radio synthesis images of polarised sources. Analytical expressions are presented for the rms noise at any location in the polarisation images. We compare these results with those for the images of unpolarised sources and discuss the usefulness of deconvolution of snap-shot images in reducing the source-noise from the off-source regions in the images.
